What is WersiClubUSA? Simply put, it’s a place for current owners along with potential owners to gather, discuss and learn about the Wersi product line or anything related to music production and simply having FUN with music!



  • The 1980’s saw Wersi introduce a digital line of instruments to the world – the CD-Line. The famous Spectra was the wonder of the 1987 Musikmesse and next to the Wersi Helios, is one of Wersi’s biggest selling instruments to date.


  • In the 1990’s, Wersi developed the digital Grand Piano line as well as digital sample based instruments and innovations such as the Livestyle upgrade for the CD-Line, Golden Gate, PhonX, Performer and the Pegasus keyboard.


  • The OAS instrument line consisted of professional arranger keyboards and organs. In 2001, the first version of the OAS instrument line was released running on OAS software… a totally open / upgradable product that over the next ten years would continue to be developed.


  • Fast forward to 2016 and we are now on the OAX (OpenArt-Xtended) generation of products with multiple models available going by the name of “Sonic”. Following in the tradition of all Wersi instruments updates to OAX are released on regular intervals adding new features with each release.

    Hi Omar,

    There are two power switches on the Scala, the mains power switch located on the mains panel at the bottom right hand of the organ base where the mains power cable is plugged in, and the On/Off switch on the organ console. The mains power switch supplies power to the organ, whilst the On/Off switch turns on the organ. The On/Off switch operates just like the power switch on a standard PC. When activated it shorts together a couple of contacts on the PC motherboard which then sends a signal to the organ’s power supply unit at the back of the console to turn on this unit and so supply power to the organ.

    As a first step, you could try the following:-

    1) Check the fuse in the mains plug
    2) Ensure that the mains power switch is turned on
    3) Check the wiring and connectors between the On/Off switch on the console and the motherboard
    4) Check the wiring and connectors between the motherboard and the power supply unit
    5) Check that the power cable that runs from the mains panel to the back of the power supply is plugged in and properly connected.

    If all the above seem OK then we may be looking at a problem with the power supply unit.

      If the previous owner ran the power chord out the back of the organ directly from the power supply the front on off switch will be bypassed.

    Hi Everyone,
    I am not familiar with any musical instruments, but I have a Wersi Scala GS 700 sitting at my house that will not turn on. Maybe I am not connecting it the right way or maybe there is something wrong with it. Can anyone give me some guidance?

    Thank you,

    Anyone hear any rumors about Wersi taking over a portion of Lowrey?

      Thanks Bill – I heard the news last night and just put a small post up on our Facebook site this morning. We had the pleasure of meeting Mark a few times when he was playing at the Dutchland Keyboard show. At the time he was playing a Spectra.

    Hi Curt
    Sorry to say but after having 5 internal problems with my OAX-1 keyboard, I did manage to fix 4 after a lot of searching, one I cannot fix as Wersi in Germany has informed me that I need a new soundboard. Hence I have found that Wersi back-up support is next to none, at least here in England.
    So I am going back to Yamaha, their back-up support is very good, I’ve always had Yamaha keyboards, but I liked the sounds etc. of the Wersi hence the reason I bought one, so now I’m exchanging my OAX-1 keyboard for the new Genos. I must say that I found Wersi Club USA members and your video tutorials very helpful.
    Regards John Simpson

      Ouch sorry to hear that John. Hopefully, you will check back in with us from time to time to see what we are up to. Please keep us updated on your musical adventures and the Genos.

      I’ve watched a few videos comparing it with the new Korg keyboard and it has some very nice rhythms and accompaniments.
